NOTE: As their name suggests hints are not exactly Medal of Honor: Frontline cheats, and are usually just simple (but very useful) tips on how you can unlock secret level, features, find hidden areas and such. Hopefully these will make playing Medal of Honor: Frontline even more entertaining.

A Chance Meeting: Falling objects
When you enter the main U-boat facility and start to fight
your way towards the docks, you will encounter several train
cars. One of these cars has a mounted MG-44. Hit the switch
on the other side of the car and it will roll until the gun
is pointing through a doorway leading into an open area between
the dockyard buildings. Use the gun to clear out the enemy.
When done, proceed forward until you find more Nazis. One
of them will shoot at you with another machine gun mounted
on a sandbagged position. Behind that are a truck full of
torpedoes and a crane that is holding several crates aloft.
Use your Springfield sniper rifle and shoot the rope. The
crates will fall on the truck, causing it to explode and kill
the sniper on the crane and any nearby Nazis.

Clipping Their Wings: Hidden chests
On the final mission where you are required to take pictures
of the blueprints, there is a sleeping area. On the side of
the room where you find the spy camera, check in between the
bunks to find hidden chests. You will find canteens inside.

Derailed: Secret passage
As you start the mission, go to your right and you will see
a dirt road. Go slow because of a Nazi that is sitting down,
waiting. You see something in the mountain. Go to the door
but do not open it. Get ready to shoot -- there are three
Nazis inside. Mow them down and grab the MG-42. Then, wipe
out the remaining Nazis below.

Nijmegen Bridge: Destroy the AA gun
At the end of the level, you will see a red barrel with a
white rag sticking out of it that must be destroyed. Use the
following trick instead of shooting the barrel or tossing
a grenade to detonate it. Approach the side of the barrel
with the rag. You should see the message "Press Action to
ignite the rag" appear at the top of the screen. Do so, and
you will hear the sound of Jimmy lighting a lighter and touching
it to the rag. Immediately back away and wait. After a few
seconds, the barrel will explode and the anti-aircraft gun
will be destroyed without wasting any ammunition.

Nijmegen Bridge: Suicidal Nazi
When instructed climb up the ladder to top of bridge, do so.
Note: Enable the "Invincibility" or "Bullet shield mode" codes
to make this easier. When you reach the top of the ladder,
a Nazi will be directly in front of you. He will aim his gun
at you and begin to shake. Do not shoot him or any other Nazis.
Wait for a moment, and he will stand up, grab his helmet,
and jump off the top of the bridge screaming.

Omaha Beach: Saving your men
When you get out of the water, quickly get to an obstacle,
then find the Higgins Boat where your lieutenant is located.
Saving your men is difficult because cannot see very far.
The will not wave at you unless you are close to them. Once
you run up and down the beach a few times, you will hear them
over the noise.

On Track: UFO
When you get outdoors next to Sturmgeist's train, look up
and to the right. You will see a UFO flying in the air. If
you look closely, it has the Nazi markings and colors.

On Track: Jimmy Patterson poster
When you get to the entrance to the train station, stop and
look on the left side of the entrance door. There will be
a wanted poster of Jimmy Patterson with a picture. It even
has a reward in German.

On Track: Drunk Nazi
You will find a bar just before the first trains. The first
person you should see is a Nazi with a mug walking around
the room. Do not shoot him. Shoot the others with guns. After
you kill the ones with guns, you can see the drunk Nazi lie
down and go to sleep on the floor, using his mug as a pillow.

Operation Repunzel: Suicidal Nazi
There is a Nazi soldier practicing a speech in a hall where
you find the map behind the painting. Instead of going around
on the top, go downstairs and run up to him. He will automatically
fall back and die without a single shot. The only downside
is that you cannot get a gold star for this mission if this
is done.

Operation Repunzel: Extra health
After you kill all the waiters and the cook, look around and
run to the bread. Jimmy will say that its yummy , and your
health will rise more than a medical canteen.

Operation Repunzel: Speech practice
You will encounter a man practicing his speech in a large
hall inside the building where they are preparing to have
a Nazi Rally. Instead of walking up to him, stay on the balcony
and go across the walkway connecting the two sides of the
room. He will see you and tell you to stop. He will then pick
up the rocket launcher next to the podium and fire it at you.
It will hit the walkway and blow it in half, forming a ramp
from the ground floor to the upper level.

Operation Repunzel: Chandelier kill
You can shoot the chandeliers that are around in some of the
rooms of the Nazi building. They will kill anyone underneath,
including you.

Rough Landing: Sniping Nazis
After Barnes blows up the tank that is inside a barn, you
will get to a mill where you will find a sniper. Kill him,
then get up to the mill. Snipe the large group of Nazis that
will appear in the distance, as if they were following you.

Seaside Stowaway: Breach wall to the docks
You will see a red barrel with a white rag sticking out of
it that must be destroyed. Use the following trick instead
of shooting the barrel or tossing a grenade to detonate it.
Approach the side of the barrel with the rag. You should see
the message "Press Action to ignite the rag" appear at the
top of the screen. Do so, and you will hear the sound of Jimmy
lighting a lighter and touching it to the rag. Immediately
back away and wait. After a few seconds, the barrel will explode
and the dock wall will be breached without wasting any ammunition.

Yard By Yard: Civilian backup
In one of the alleys, you will encounter an old women just
sitting in her backyard. Next door to her lives a young man
with glasses, lying on his lawn next to his shed. In his yard
is a ladder propped up on a couple of boxes. Use this ladder
as a ramp and walk across it. In this yard is a man with a
helmet standing next to his shed. Do not shoot him. Walk up
closely to him and he should have his arms raised, is clearly
too old to be in the military. Stare at him until he puts
his arms down and reaches into his shed window for a shotgun.
Still, do not shoot him. By this time a Nazi soldier will
storm into the man's yard. The old man will fire at him, killing
him, and leave his yard looking for more Nazis. For good measure,
stand as close to him as possible while he leaves his yard.
He will give you a nudge to go while he covers you.

Yard By Yard: Create hole
Shoot the dirt with a Panzerschreck and the man will sink
down into a hole.

Yard By Yard: Flush the toilet
At the beginning of the mission in the first house you enter,
go up the stairs to find a bathroom. Press Action here and
Jimmy will flush the toilet.

Your Finest Hour: Soldiers' names
After your amphibious boat explodes, go to the shore where
you will see a few dead men. Zoom in on there chest and you
will see names such as Rus K (Risky) and others.

Your Finest Hour: Fish
In the first mission, Your Finest Hour, walk along the beach
and you can see little silver fish that have washed up on
shore.
